Maybe you should read my reasoning before you scoff at my answer. The riddle asks how many kits, cats, sacks, or wives are going to St. Ives. You are none of those.
If I said to you, "Die Hard movies, how many do you own?" (sure it is a bit odd in the wording, but it is poetic), would you answer with, "Well I own Clueless, so I guess that's one"? No, cause I didn't bloody ask about Clueless, just as the originator of the riddle didn't ask about you.

Actually, this little rhyme is a Guinness World Record. It is the oldest mathematical puzzle being 3650 years old. The riddle was found on the Rhind Papyrus which was dated to be from about 1650 BC. The fact that the scribe Ahmes (no, not the department store, Sirius) probably used hieroglyphics to document his riddle suggests that the words have been altered slightly in translation, though the riddle remains the same. And the answer, one, is not the generally accepted answer, it is the answer. The answer is actually on the scroll, but regardless, think about it... the riddle does go, “As I was going to St. Ives…”. Well, duh, I equates to one.
